Abstract
A stack of closure plates with slots are slipped over a cable passing through an aperture in a wall of a radiation containment enclosure and affixed to the enclosure wall. The slots of the plates are staggered with alternate plates bearing on opposite sides of the cable to secure the cable and impede leakage of radiation through the aperture and along the cable.

Brief '' ,, of the I~ liv~
This invention relates to r~nn(~cfinF to electrical ~Ja-aLus within a radiation crntqininF enclosure.
It is ~.,. I ;...."1 desired to reduce the broadcast of ~ radiation from some piece of electrical a~l~aldLus. This may be accomplished by enclosing the radiating ~ Ua~Ui~ in a metal enclosure. Method and alJlJ~aLus according to this invention provides for ,r~nn~rtinF a~ uaiu~ 80 enclosed to ~y~a~al,us outside the enclosure that is effective in avoiding radiation leaks and is both as to rnaterials and in~tqlP~ n labor.
The invention features an aperture in an enclosure wall large enough to permit passage of a connector fitting on the end of a cable, After the connectorfitting is passed through the aperture, a stack of closure plates with slots areslipped over the cable and affixed to the enclosure wall. The slots of the plates are staggered with alternate plates bearing on opposite side of the cable to secure the cable and impede leakage of radiation through the aperture and along the cable.
Brief D~L~ ,t; ~ of the Drawings Figure 1 shows ~ within an enclosure (part of the enclosure shown cut away) connected to a~ u~ outside the enclosure according to the invention.
Figure 2 shows a closure plate used in the invention.
Figure 3 shows in detail the structure of the enclosure of Figure 1 in the vicinity of the place where a cable enters the enclosure.
Detailed D~..~;~li~
The invention may be described with reference to the Figures.
Enclosure 10 has an enclosing wall 11 made of e~ectrically conductive material which defines an interior and e terior space. Electrical a~J~ala~U:~ 12which emits el~ tir radiation, the broadcast of which is undesirable, is situated withm enclosure 10. Another electrical a~ , alu: l 13 outside of enclosure 10 is connected by cable 14 to a~lJ~a~us 12. Cable 14 has the form of a ribbon with parallel conductors 15 Iying side by side and extending the length of the cable. Cable 14 runs into enclosure 10 through closure structure 16 and aperture wo95/26621 Pcrlu~94111332 ~lsoa~7 17 and is ~ d in connector fitting 18, which is smaller than aperture 17.
Closure structure 16 includes a stack 20 of id0ntical closure plates 19. As shown particularly in Figure 2, each closure plate 1g is made from flat metal stock and has a generally rectangular shape with two longer edges 21, 24 arld two shorter edges 22, 25. Slot 23 .. ;. ~ with shorter edge 22, and is wider than ribbon cable 14, but not as wide as connector fitting 18. Slot 23 runs generally parallel to longer edges 21, 24, and is closer to edge 24 than to edge 21.
Holes 26, 27 provide ~ a~;~ for clamping devices.
The~ .. ~.l;.. ~ofa~J~al~llu~12toalJlJ~alu~13isZ .. ~ l.P~asfollows.
Csble 14 is connected at one of its ends to a~Ja~ àlud 13. The other end of cable 14 is ~....;...~Pd im connector fitting 18 Cormector fitting 18 is then passed through aperture 17 into the interior or enclosure 10 and connected to a mating fitting of a~aluts 12. Closure plates 19 are p(.~ ...ed in a stack covering aperture 17 with cable 14 in the slots of the closure plates, as shown particularly in Figure 3.
The plates are arranged irl the stack in a first and second set with plates of the first and of the second set iul. .l~v~d in the stack. As shown in Figure 3, plates 1g and 30 are members of the first set, and plates 31 and 32 are members of the second set. Although all the plates are identicsl, those of the first set are dilf~ . ~lly oriented in the stack from those of the second set. In 1)~ L. .ll ~, the plates of the second set are rotated 180 degrees around an axis ~ ...l;. ..lzr to the plates with respect to the plates of the first sei. This means that the blind ends of the slots of the plates of the second set will be on opposite sides of the stack from those of the first set, and also that the longer edges that are closer to the slot of the second set of plates will be on the opposite side of the stack from the longer edges which are closer to the slot of the first se~ of plates.
The described arrangement of the plates in the stack produces the ~v,lL~ul~ shown in Figure 3, where the edges of plates of the first set protrudebeyond those of the second set at the bottom while the edges of the plates of the second protrude at the top.
When the plates have been arrsnged as described, the stack is squeezed together by pressing on the protruding edges 80 that the plates of the first set bear ~ WO 95/26621 ~ 7 PCTNS94/11332 ., .
against the bottom of cable 14, while the plates of the second set bear against the top of the cable. Wbile the plates are so squeezed, the stack is affixed to all 11 of enclosure 10 by some clamping device such as screws 28 passing through holes 26 and 27.
